MACHINE FOR TRIMMING WIRE SPOKES.

SPECIFICATION forming part of Letters Patent No. 403,347, dated May 14, 1889.

, Application filed October 29, 1888- Serial No. 289,361. (No model.)

To all whom it may concern:

Be it known that I, FRANK H. HARRIS, a citizen of theUnited States, residing at Auburndale, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Machines for Trimming Wire Spokes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in machines for trimming wire spokes, and the machine is intended to be used in the manufacture of iron wheels,wherein it is necessary to cut off the ends of the wire spokes after they are secured to the hub of the wheel and before the rim can be secured thereto. 7

To this end my invention consists in the peculiar construction, arrangement, and combination of a slidingly-adjustable wheel support or supports with rotary cutters placed in proper relation thereto and suitably constructed to effect the object of my invention, all as more fully hereinafter described, and shown in the following drawings, in which Figure 1 is a side elevation of my improved machine. Fig. 2 is a section on line mm. Fig. 3 is a cross-section on line n y, and Fig. 4 is a cross-section on line .2 z.

A is the bed or table of the machine, supported on suitable legs, B.

O C are vertical standards secured upon the bed at one end of the machine. D D are shafts longitudinally journaled in these standards in vertical plane with each other.

The lower shaft is provided at its outer end with a suitable drive-pulley, E, to which the power is applied, and between the standards with a gear wheel, F, which meshes with the gear-wheel G, of the same diameter, upon the upper shaft, and by means of which both shafts are made to revolve with the same speed and in opposite directions to each other, as shown by the arrows in Fig. 3. To the inner end of the upper shaft is secured the cutter-disk H,-provided with a beveled cuttingedge, I. The lower shaft has secured upon its inner end the disk J, which is beveled inversely to the cutter-disk H and provided with a series of spoke-notches, K, upon its circumference spaced at equal distances apart. These two disks are mounted in such relative position to each other that the cutting-edge I of the upper disk slightly overlaps the lower disk to the depth of the spoke-notches, more or less, and so that the cutting-edge of the upper disk revolves in close proximity to the rear side of the lower disk.

L is a longitudinal slot in the bed of the machine, and in this slot is slidingly adjustably secured the wheel-support M, which carries an upwardly-projecting stub-shaft, N, upon which the hub of the wheel is adapted to be engaged. This wheel-support- M is provided with a suitable index finger, O, by means of which and a suitable scale on the bed operating in connection therewith the longitudinal distance of the stub shaft N from the cutter-disk H is indicated, and may be accurately adjusted any desired distance therefrom. A similar Wheel-support, P, is slidingly adjustably mounted upon the bed, and this is adapted for such class of wheels secured upon a shaft, such as the drive-wheels of velocipedes. To this end it is provided at its upper end with a socket, Q, to receive one end of the shaft of the wheel, while an arm, R, hinged to a standard, T, at the rear end of the machine, is provided with a socket, S, upon its free end to receive the other end of the shaft of the Wheel. When not in use, the arm B may be thrown up and out of the way and held in' vertical position by a suitable counter -weight, U, secured upon the outer end of the arm.

In practice the parts being constructed substantially as shown and described, they are intended to operate as follows: Let us suppose the wheel to be operated upon to be one of the ordinary kind-that is, not provided with a shaft. Such a wheel is engaged upon the stub -shaft N of the wheel-support M, which latter is adjusted the proper distance from the cutter-disklto out the spokes at the proper length. Upon motion being given to the rotary disks, the operator by a movement of his hand causes the wheel to turn upon the stub-shaft N, and thereby introduces one spoke after another between the rotary disks. The end of the spoke is thereby engaged into one of the spoke-notches upon the side where the disks approach each other, and is carried thereby under the cutting-edge of the cutterdisk H, which cuts off the end which may project beyond the lower disk. In this manner all the spokes are successively introduced between the disks, and the spokes of the whole wheel are thus trimmed as fast as the oper- 5 ator is enabled to carry the spokes through the disks, depending only upon the speed of the disks. 'lo trim the spokes of a wheel having its shaftalready secured, the wheelsupport M is dispensed with and the wheel I0 is engaged upon the wheel-support P and engaged with the upper end of its shaft into the aperture of the hinged arm R. By similar manipulation of the wheel the spokes are then cut oil in the same manner as before described.

Vhat I claim as my invention is- 1. In a machine for the purpose described, the combination, with the bed, of a slidinglyadjustable wheel-support and of two rotary disks, the lower one being provided with 20 spoke-notches and the upper one with a cutting-edge adapted to cut off the ends of the spoke, in conjunction with the lower disk, into the notches of which the ends of the spokes are adapted to be engaged, all substan- 2 5 tially as described.

2. The combination, with the frame of the machine and the rotary disks I and I,ada-pted to cut off the ends of the spokes, of the wheel-support I, slidingly adj ustably secured on the bed of the machine and provided with a receiving-socket for the shaft of the wheel, and of the hinged arm R, having a corresponding socket to engage With the upper end of the shaft of the wheel, all substantially as described.

3. In a machine for the purpose described, the combination, with the bed of the machine,

of the rotary disks I and J, revolving in op-
